What will be the new frequency of the wave if the new wavelength of the wave is four times its old wavelength? The wavelength of a wave is defined as the distance between any two successive crests or troughs of the wave. However, the material itself does not move along with the wave. This basically means that when the wavelength is . Wavelength is described as the distance between a trough to a trough or a crest to a crest. The distance traveled by the wave in a unit of time is called the velocity of a wave or wave velocity. A fire ant, searching for hot sauce in a picnic area, goes As the frequency decreases, the wavelength gets longer. The equation can be rewritten to calculate wavelength (and frequency), speed of light and Plank constant. 1 ngstrom = 1 x 10-10 m. 1. So, as the energy decreases, wavelength increases and vice versa as the energy of the radiation is inversely proportional to the wavelength of the radiation. Being massless, photons always travel at maximum speedthe speed of light (c)but possess different wavelengths.
